This unit introduces the present continuous tense (also called the present progressive tense) in English. The present continuous is used to talk about actions or situations that are happening or in progress at the time of speaking. It is formed using the present tense of the verb "to be" (am, is, are) plus the -ing form of the main verb. Some examples of when to use the present continuous are provided, such as to talk about temporary actions in progress or planned future events. Exercises are then provided to practice forming and using the present continuous tense.
